MACHINE FOR CONFIGURING GLASS-MAKING ROLLS.

SPECIFICATION forming part of Letters Patent N o. 653,299, dated July 10, 1900.

Application filed September 25, 1899 Serial No. 731,604. (No model.)

To @ZZ whom t may concern:

Be it known that I, Ci-IARLns LAMBRECHT, a citizen of the United States, residing at the city of St.' Louis, in the State of Missouri, have invented a certain new and useful Improvement in Mechanism for Configuring Glass- Making Rolls, of which the following is afull, clear, and exact description, such as will enable others skilled in the art to which it ap- 1o pertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is an end elevational view of the lower portion of myim proved mechanism for configuring glass-making rolls, the upper part of the machine being omitted. Fig. 2 is a top plan view of a portion of said machine. Fig. 3 is an enlarged sectional view on line 3 3, Fig. 1. Fig. 4 is a detail view of a bracket zo secured to the planer-bed. Fig. 5 is an end elevational view of a modified form of the mechanism. Fig. Gis a top plan view of a portion of the same, and Fig. 7 is an end elevational view of another modified form of z5 the mechanism.

This invention relates toa new and useful improvement in mechanism for configuring rolls for use in the manufacture of sheet-glass, and is designed particularly for use in connec- 3o tion with the production of rolls for making prismatic glass, wherein curvilinear prisms are formed on one or both faces of a sheet of glass. p A

My present invention consists in an im- 3 5 proved mechanism adapted for use in connection with an ordinary planer, whereby longitudinally-disposed serpentine grooves and ridges are formed on the face of a glass-making roll, as will hereinafter be described and 4o afterward pointed out in the claims.

In the drawings, A indicates the base or frame of an ordinary planingmachine, B B the standards rising from each side thereof, and C the cross-railcarryin g the cutting-tool.

I have omitted several details of the planer, as the same form no part of my present invention.

D indicates the bed of the planer, which in operation reciprocates, said bed being provided with the usual grooves b for the purpose of clamping the work thereon.

E indicates suitable bearings, or stocks, as they are sometimes called, clamped to the bed D for supporting the roll in position to be operated upon by the cutting-tool. This roll is free to rotate in its bearings and, with its associate parts, has reciprocatory movement under the cutting-tool, the travel of the planerbed .also imparting an oscillating 6o movement to the roll in its travel to eect a serpentine cut by the tool engaging the periphery of said roller.

I will now describe the mechanism employed for communicating an oscillating movement to the roll in its travel.

H indicates a rack-bar secured to one of the standards B and preferably suitably supported at its ends. This rack-bar is stationary.

I indicates a bracket secured to the planer- 7o bed, on which are adjustably mounted bearin position :ings e', carrying atran of gearing J, one of which is in mesh with the rack H, while another is connected to a crank-shaftj, carrying fa wrist or crank pin j. on its inner end.

K indicates a pitman engaging the crankpin, the upper end of said pitman being con-` nected to a rock-arm L, clamped to the axle of the roll. The cutting-tool being placed in the proper position relative to the roll, the 8o power is imparted to the planer, so that its bed will reciprocate. The cutting-tool makes its cut, and as the bed and its carried roller move longitudinally the train of gearing in mesh with the .fixed rack causes the shaft j to rotate, and the crank on the inner end thereof will rock the arm L, so that the roll is caused to oscillate during its longitudinal movement, such oscillation causing the cut ting-tool to effect a serpentine or curvilinear 9o cut. As the cutting-tool must cut a certain depth in to the periphery of the roll, it follows that, as said tool is stationary, it must be main-v tained at such fixed relation relative to the surface of the roll to be cut, and to secure the serpentine line the roll must be oscillated. Were the :roll or the cutter moved laterally to effect the serpentine cut the depth of the grooves would be less on each side of the vertical line drawn through the center of the roll loo until a point was reached wherein the cutter would not engage the roll at all.

By increasingor diminishing the throw of the crank j' the radius of the crescent described on the surface of the roll may be increased or diminished thereby, as desired, and by changing the train of gearing J a like result willfollow. As the surface of the roll is to be divided in such manner that the grooves shall be certain distances apart, I tix a templet M on the axle of the roll and provide the same With a series of perforations cooperating with bolts m, engaging the rockarm L. After a groove has been cut the proper depth the bolts or one of them is Withdrawn from engagement With the rockarm and said arm unclamped from the axle, so that the roller and its templet M can be rotated until the next perforation either in the inner or outer circle of the templet registers with one of the openings in the rockarm, when the bolt is introduced to hold the roller in its new position relative to the rockarm, after which the clamping-screw on the rock-arm is operated to firmly clamp said arm on the axle of the roller and-so take the strain from the bolt m.

In Figs. 5 and 6 I have shown a modiiied form of mechanism wherein the pitman N, having a link connection with the rock-arm L, carries a roller n at its outer end, which runs in a cam-groove O of a stationary templet P, secured in some suitable support.

In Fig. 7 is another form of mechanism, in which shaft j, instead of being provided with a crank, has mounted thereon a peripherallyfaced cam Q, in which groove runs a roller r on a pitman R, having a link connection with the rock-arm L.

I am aware that minor changes in the arrangement, construction, and combination of several parts of my device can be made and substituted for those herein shown and described Without in the least departing from the nature and principle of my invention.

Having thus described my invention,what I claim, and desire to secure by Letters Patent, is-

1. In a machine for configuring rolls, the combination of a reciprocating bed, means for supporting the roll thereon, a cutter, a rock-arm adapted to be secured directly to the roll, mechanism carried by the bed and connected to said rock-arm for rocking the same, and a stationary element coperating with said mechanism for imparting motion thereto, substantially as described.

2. In a machine for configuring rolls, the combination of a reciprocating bed, means for supporting the roll thereon, a cutter, a rock-arm adapted to be secured to the roll, a rotatable device carried by the reciprocating bed, mechanism between said rotatable device and said arm for reciprocating the latter, and a stationary element cooperating with said rotatable device for rotating the same,

substantially as described.

3. In a machine for configuring rolls, the

combination of a reciprocating bed, means for supporting the roll thereon, a cutter, a rock-arm adapted to be secured to said roll, mechanism carried by the reciprocating bed and connected to the rock-arm for rocking the same, a stationary element coperating With said mechanism for-imparting motion thereto, and a templet adapted to be secured to the roll and to the rock-arm for holding the roll in adjusted positions, substantially as described.

In testimony whereof I hereunto affix my signature, in the presence of two Witnesses, this 13th day of September, 1899.

CHARLES LAMBRECHT.
